Fig. 13 is a side view of the rear half of the underframe with the sidesill removed; and

Fig. 14 is a side view of the front half of the underframe with the sideand front sills removed.

The reference numeral 2 indicates the underframe (only incidentallyshown) of the locomotive on which is mounted similar `side frames 4 andend frames 3 and 5. The underframe includes U-shaped center sill members6 extending the full length thereof, angle side sills 8, rear channelsill 10 and curved front channel sill 12. The rear legs of the frontsill are welded to the forward ends of the side sills, the rear ends ofthe side sills are welded to the rear sill and the ends of the centersills are welded to the front and rear sills. Similar rear and forwardbolster structures 14 and 16, respectively, extend transversely of theunderframe and are secured to the side frames and center sill members.Cross bearer 18 extends transversely of the underframe, centrallybetween the bolsters, and is secured to the side sills and underframemembers. Angle members 34 are arranged above the side ice sills 8 inadvance of and at the rear of the rear bolster and an outer cover plate91 is welded to members 34 and 8 closing the space therebetween. Bracemembers 93, see Figs. 5, 6 and 8, are welded between the side sill andmembers 34.

As previously stated, the side frame structures 4 are similar andreferences may be had to Figs. 2, 4, 6 and 9 through 12 for details ofthe same. Numeral 38 indicates the rear end post in advance of which areside posts 42, door posts 44 and 50 and front posts 51' and 51". Posts42 and 44 are continuous and are assembled with the base portions to theoutside and their lower ends inside of the vertical flange of the sidesill 8, the adjacent portions of such posts and side sill being weldedtogether. Front posts 51 and 51" are welded to the front sill 12. Roofside angle plate 44) is secured on the top of the end post and posts 42,44 and 51 and 51, the base flange of the side roof plate and theadjacent post ends being welded together. Angle brace 46 extends beneaththe roof plate between front posts 42 and 44 and is welded to suchmembers.

Door post 50 has a rearwardly extending horizontal leg or brace member51 welded thereto and such unit is `detachably secured in the sideframe. Upper and lower brackets 52 and 53 are welded to the ends of post50 and bracket 54 is welded to the rear end of member 51. The upperbracket 52 is secured to the brace member 46 by bolts 55, the lowerbracket is secured on top of the front end sill 12 by bolts 56 andbracket S4 is secured to the adjacent side post 42 by bolts 57. One ofthe detachable door post structures must be removed to providesutlicient clearance when moving an auxiliary power plant endwise from afront side of the locomotive,

Sectional side posts are assembled between some of the side posts andeach comprises a lower section 58 and an upper section 59. Sections 58are U-shaped in cross section an-d the base portions thereof lie insidethe vertical flange of the side sill and rest on the horizontal portionof the side sills, the base portions of the posts being welded to theside sills. U-shaped in cross section but of less width and greaterdepth than sections 58 and are located inwardly thereof. An angle beltrail 60 extends longitudinally from a rear post 44 to front post 42 andis welded thereto at its ends. This belt rail lies over the tops of thelower post sections 58 and the top flange is cut out to receive posts 42and 66. Filler plates 62 are welded inside of the inner flanges of theposts 44 adjacent the belt rail. Post sections 59 have a base member 63and a top member 103 welded between their parallel flanges, such membersprojecting outside of the post sections. The lower ends of the parallelanges of post sections 59 extend below the base members, see Figs. 3 and7, and are welded' to the inner face of the angle belt rail 60. Theupper ends of post sections 59 lie adjacent the inside of the inner faceof roof plate 40 and are wel-ded thereto. Top

members 103 project under and are welded to roof plate 40 and bottommember 63 overlies rail 60 and is Welded thereto.

Posts 42 have radiator supporting plates 105 fixed outside of theirflanges and extend inwardly approximately the same distance as andparallel to the anges of post sections 59, see Fig. 2. The lower endsIof plates 105 are formed to rest on the inner top face and against theupper rear face of the belt rail 60 to which they are welded. The upperends of such plates lie inside of the roof plate and are welded thereto.

Longitudinal brace members are welded to end post 38, and the adjacentpost 42 and between such post 42 and the rear post 44. Horizontal bracemembers 97 and 99 extend between front posts 44 and 51 and are weldedthereto and to post 51". A top door frame Sections 59 are also 3 member101 is welded between rear posts 44. An intermediate belt rail 64 liesbetween belt rail 60 and the side sill and is wel-ded to the inner edgesof the flanges of posts 42,- 66 and 58. Bracket strips 46 extendbetween' p'ostsf 42 in front of and above the belt rail 60 and areweldedl to such rail and posts. extend' between front and rear posts 42andadjacent posts 66 over the belt rail 60 and are weldedthereto,thebracketstrips having their ends cut away to clear theHsides of theposts 42. Truss angle members 65 ex* tendv from the base portions ofpost sections 58 to the belt rail'adjacent posts 42, from rear post 44to post 42 in advance, thereof and from the front post 42 to post 42therebehin'd. Members 65 are welded to the side sill, belt railsandadjacent posts; of. rear post `44 and to the rear of front post 42,extend between and are welded to belt rails 64 and 60 and roof plate40.

Thespaces between the roof plate 40, belt rail 60 and posts'w42, abovepost sections 58, provide inlet openingsy through which air passes tothe water cooling systems for'the engines or" the main power units.Frames formed of; welded together angle members 67 carrying shutters 68are arranged in such air inlet spaces and are secured bybolts67todepending brackets 69 welded to the roof plate, brackety strips 46Aand brackets 41 welded to the sides` ofy posts' 42. Similar shuttercarrying frames are arranged and similarly secured in end spaces abovethe belt'rail 60 adjacent the spaces between post 66 and adjacent.l post42. These frames 67 provide inlets through which air flows to the watercooling systems of the auxiliary'and main power plants.

The!` spaces between belt rail 60 and rail 64 therebelow form openingsthrough which Ventilating air flows to the; interior' of the locomotivepower chamber.
